Abstract
Description
Technical Field
[0001] This utility model relates to the field of ramp protection technology, specifically a ramp protection device for urban expressways. Background Technology
[0002] Urban expressway ramps refer to road sections that connect urban expressways with adjacent auxiliary roads or other main roads. They are usually designed as overpasses, ramps, or access roads for vehicles to enter and exit the expressway system.
[0003] Currently, guardrails at urban expressway ramps are usually made of steel or concrete. When vehicles collide with guardrails at high speeds entering the ramp, the damage to the vehicles is significant and can easily cause injuries or fatalities. Therefore, we propose a protective device for urban expressway ramps. Utility Model Content
[0004] The purpose of this utility model is to provide a protective device for urban expressway ramps, which can buffer and guide vehicles when they collide with the ramps, thereby reducing the damage to the vehicles and greatly reducing the possibility of personal injury. It solves the problem that the guardrails at urban expressway ramps are usually made of steel or concrete, and when vehicles collide with the guardrails at high speeds, the damage to the vehicles is greater and personal injury is more likely.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for urban expressway ramps, comprising a rotating barrel and a C-shaped trough frame. Two rotating arms are rotatably mounted inside the C-shaped trough frame via a rotating arm shaft. A rotating barrel is rotatably mounted at the end of each rotating arm via a rotating shaft. A rotating sleeve is rotatably mounted inside the C-shaped trough frame near the rotating arm shaft via a sleeve shaft. A buffer spring is installed inside the rotating sleeve. A sliding rod is slidably mounted inside the rotating sleeve, and a connecting shaft is rotatably connected to one end of the sliding rod outside the rotating sleeve. Both ends of the connecting shaft are fixedly connected to opposite sides of the outer surfaces of the two rotating arms.
[0006] Preferably, a piston block is fixedly connected to one end of the slide rod located inside the rotating sleeve.
[0007] Preferably, a scraper ring is fixedly installed at one end of the rotating sleeve near the slide rod, and the slide rod passes through the scraper ring.
[0008] Preferably, a warning board is fixedly installed on the upper surface of the C-shaped slot frame, and a warning sticker is fixedly installed on the front surface of the warning board.
[0009] Preferably, the included angle between the swing arm and the C-shaped slot frame is 85° > a > 45°.
[0010] Preferably, the rotating drum is provided with a buffer filler.
[0011] Preferably, a rubber buffer layer is fixedly installed on the outer surface of the rotating barrel.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a C-shaped trough frame, a rotating barrel, a rotating arm, a rotating arm shaft, a rotating sleeve, a sleeve shaft, a connecting shaft, a sliding rod, and a buffer spring, achieves the effect of buffering and guiding vehicles when they collide at the entrance of an urban expressway ramp, thereby reducing the damage to the vehicle and greatly reducing the possibility of personal injury or death. The C-shaped trough frame is fixedly installed at the original guardrail position at the entrance of the urban expressway ramp. When a vehicle enters the ramp and a collision occurs, the vehicle will come into contact with the rotating barrel. The rotating barrel rotates under force, which also causes the rotating arm to rotate. The sliding rod slides into the rotating sleeve and compresses the buffer spring, thereby buffering the vehicle during the collision. The rotating barrel and rotating arm also guide the impacting vehicle, causing it to move towards the middle of the road at the ramp entrance, thereby reducing the impact damage to the vehicle and providing better protection for the people inside the vehicle.
[0014] 2. By setting up warning signs and stickers, this utility model serves to warn vehicles entering the gate of an urban expressway, thereby preventing vehicle collisions.
[0015] 3. By setting a rubber buffer outer layer, this utility model can buffer and protect the outer surface of the rotating barrel when the vehicle hits it, so as to avoid damage to the surface of the rotating barrel when it is impacted.
[0016] 4. By setting a hanging ring, the dust and impurities adhering to the outer surface of the slide rod are scraped off by the scraping ring when the slide rod slides into the rotating sleeve, so as to avoid dust and impurities entering the interior of the rotating sleeve and causing wear on the inner wall.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1
[0024] like Figures 1-5 As shown, this utility model proposes a protective device for urban expressway ramp entrances, comprising a rotating barrel 2 and a C-shaped trough frame 6. Two rotating arms 3 are rotatably mounted inside the C-shaped trough frame 6 via a rotating shaft 15. The rotating barrel 2 is rotatably mounted at the end of each rotating arm 3 via a rotating shaft 1, positioned between the two rotating arms 3. The included angle between the rotating arms 3 and the C-shaped trough frame 6 is 85° > α > 45°. The angle α causes the rotating arms 3 to tilt towards the direction of vehicle travel at the urban expressway ramp entrance, thus facilitating the rotation of the rotating arms 3 when a vehicle impacts the rotating barrel 2. The main body of the rotating barrel 3 is made of elastic composite materials such as polyurethane. A buffer filler 13 is installed inside the rotating barrel 2. When the rotating barrel 2 is impacted by a vehicle, the buffer filler 13 absorbs energy and cushions the impact. A rubber buffer outer layer 14 is fixedly installed on the outer surface of the rotating barrel 2. When the vehicle hits the rotating barrel 2, the rubber buffer outer layer 14 plays a buffering and protective role on the outer surface of the rotating barrel 2 to avoid damage to the surface of the rotating barrel 2 when it is impacted. A rotating sleeve 5 is rotatably installed inside the C-shaped slot frame 6 near the rotating arm shaft 15 via a sleeve shaft 16. A buffer spring 10 is installed inside the rotating sleeve 5. A slide rod 9 is slidably installed inside the rotating sleeve 5. A connecting shaft 4 is rotatably connected to one end of the slide rod 9 outside the rotating sleeve 5. The two ends of the connecting shaft 4 are fixedly connected to opposite sides of the outer surface of the two rotating arms 3. A piston block 11 is fixedly connected to one end of the slide rod 9 inside the rotating sleeve 5. When the slide rod 9 slides into the rotating sleeve 5, the piston block 11 compresses the air inside the rotating sleeve 5.
[0025] In use, the C-shaped slot frame 6 is fixedly installed at the original guardrail position at the ramp entrance of the urban expressway. When a vehicle enters the ramp entrance and an impact occurs, the vehicle will come into contact with the rotating barrel 2. The rotating barrel 2 rotates under force, which also causes the rotating arm 3 to rotate. The sliding rod 9 slides into the rotating sleeve 5 and compresses the buffer spring 10. The piston block 11 also compresses the air inside the rotating sleeve 5, thereby buffering the vehicle during the impact. The rotating barrel 2 and rotating arm 3 guide the impacting vehicle, causing it to move towards the middle of the road at the ramp entrance, thereby reducing the impact damage to the vehicle and providing better protection for the people inside the vehicle. Example 2
[0026] like Figures 1-3 As shown, the present invention proposes a protective device for urban expressway ramp entrances. Compared with Embodiment 1, this embodiment further includes a scraper ring 12 fixedly installed at one end of the rotating sleeve 5 near the sliding rod 9, and the sliding rod 9 passes through the scraper ring 12. A warning plate 7 is fixedly installed on the upper surface of the C-shaped slot frame 6, and a warning sticker 8 is fixedly installed on the front surface of the warning plate 7. The warning sticker 8 serves to warn vehicles entering the urban expressway ramp entrance to avoid vehicle collisions.
[0027] In this embodiment, when the slide rod 9 slides into the rotating sleeve 5, the dust and impurities adhering to the outer surface of the slide rod 9 are scraped off by the scraper ring 12 to prevent dust and impurities from entering the rotating sleeve 5 and causing wear on the inner wall.
[0028] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
